Unlock PDF

Unlock PDF takes the password protection off a PDF when you already know the password. Bank statements, payslips, tax notices, phone bills and school reports often arrive locked with your date of birth or an account number, which means typing it every time you open the file, and many other tools — including our merge, split and compress tools — can’t work with it at all. Unlock it once and the copy you download opens straight away.

It also handles the other kind of protection: files that open freely but are set to block printing, copying text or editing. Those have no password to type. The tool spots them and removes the restrictions in one click.

This is not a password cracker. It cannot find, guess or bypass a password you don’t have, and it won’t try. If the password is wrong, it simply says so.

Everything happens in your browser. The file and the password stay on your device and are never sent anywhere. The pages are not redrawn or turned into pictures, so the text stays sharp, searchable and copyable, and links, bookmarks and form fields are kept.

1. Tap “Choose a PDF” or drop your file onto the box. The tool checks what kind of protection it has.
2. If it needs a password, type it into the Password box. Press “Show” to check what you typed.
3. Press “Unlock PDF”. For files that only block printing or copying, press “Remove restrictions” instead — no password needed.
4. Press “Download PDF” to save the unlocked copy. Your original file is not changed.

• Removes the open password when you type it, or the owner password if that is the one you have.
• Removes print, copy, edit, comment and form-filling restrictions, and lists which ones the file had.
• Works with the standard PDF password protection: RC4 (40 and 128-bit), AES-128 and AES-256.
• The unlocked copy keeps real text: nothing is printed to images, so it stays searchable and the file size barely changes.
• Before you download, the new file is reopened with no password to check the lock is really gone.
• Clear messages for a wrong password, a file that isn’t locked, and protection that can’t be removed.
• The decryption runs in a background worker, so the page stays responsive with big files.

• Passwords are case-sensitive. Bank and government PDFs often use a date of birth in a set format (such as DDMMYYYY) or part of an account number; the email or letter that came with the file usually says which.
• If the file was protected by someone else, only remove the password if you’re allowed to. Unlocking doesn’t change who owns the content.
• PDFs locked to a digital certificate (common in some company systems) instead of a password can’t be unlocked here.
• Digital signatures inside a locked file will usually show as invalid after unlocking, because the file has been re-saved.
• Once unlocked, the file can go straight into Merge, Split, Compress or Sign PDF using the links that appear after the result.
